Blockchain Crypto Currency Art
World’s Oldest Blockchain is in the New York Times Since 1995 invented by cryptographers Stuart Haber and Scott Stornetta @absoluteproof
Instead of posting customer hashes to a public digital ledger, Surety creates a unique hash value of all the new seals added to the database each week and publishes this hash value in the New York Times. The hash is placed in a small ad in the Times classified section under the heading “Notices & Lost and Found” and has appeared once a week since 1995.
The longest running blockchain started in 1995 and is still running strong today. Current hash circled in red. Based on Stuart Haber and W. Scott Stornetta https://t.co/q1VIUvwGUA pic.twitter.com/eGEhqFSl7U— Ittai Abraham (@ittaia) August 23, 2018
